I do not have access to the full text of the article "The effects of government-led cash transfer programs on behavioral and health determinants of mortality: a difference-in-differences study". The search results provided do not contain the content of this medical article, but rather documents focused on financial systems, pensions and financial literacy in Slovakia. In order to create an accurate and factual summary as per your requirements, I need access to the full text of the article. Without it, I cannot verify the specific findings, statistics, and conclusions of the study, which would violate your requirement for verified facts and no speculation. Please provide me with the full text of the article or its abstract so I can create a quality summary.
